This guide covers How to Find the Time in Another Country | TimeFlow — what it means, how it works, and how to use it. The explanations below are followed by worked examples with real dates and real times, a set of frequently asked questions, and links to the tools that do the calculation for you: the time zone converter, the world clock, and the UTC converter. Where a number is given — an offset, a date, a count — it is computed from the IANA Time Zone Database for the date stated, not copied from a table that may be out of date.
Try the tool: Time Zone Converter — convert any time between any two cities, with the daylight saving rules for the date you choose.
The fastest way to find the time in another country is a world clock: type the city, and the tool shows the current local time, date and offset. The world clock on this site lists 100 cities, and the time-in-city tool covers any city in the IANA database.
If you need to work it out by hand, find the country's UTC offset and add it to UTC. Japan is UTC+09:00 all year, so the time in Tokyo is always UTC plus 9 hours. India is UTC+05:30 all year. The United Kingdom is UTC+0 in winter and UTC+01:00 in summer. The United States has four mainland time zones, from UTC−05:00 in New York to UTC−08:00 in Los Angeles in winter.
The complications are the usual ones: daylight saving, half-hour offsets and countries with more than one time zone. The United States, Canada, Mexico, Brazil, Russia, Australia and Indonesia all span several zones, so 'the time in Russia' is not one time — Moscow is UTC+03:00, Vladivostok is UTC+10:00. Always name the city, not just the country.
For scheduling, the time is only half the question — the other half is whether the person is awake and working. A world clock tells you the time; the meeting planner on this site tells you the overlap between two cities' working days, which is what you actually need to schedule a call.
In practice
The fastest way is the world clock, which shows the current time in every major city, with the date and the offset. Type the city, and the time appears — no calculation, no lookup, and no risk of getting the offset wrong. The world clock also shows whether it is a reasonable hour to call: a green indicator for working hours, amber for the evening, and red for the middle of the night.
The second way is to search for the city on this site. Every major city has its own page — the world clock for Tokyo, for example — with the current time, the offset, the daylight saving dates, and the time difference from the other major cities. The page also shows the best time to call from your city, and the overlap of working hours.
The third way is to learn the offset. If you call the same city every week, memorise its offset from UTC and the dates it changes its clocks — and remember that the offset is not the same all year if the city observes daylight saving. The time zone converter converts any time between any two cities, and the meeting planner finds the times that suit everyone.
The numbers: what 12:00 UTC looks like around the world
The table below shows the local time in eight major cities when it is 12:00 UTC on 15 January 2026. The spread is the whole point of time zones: the same moment is a morning in New York, midday in London, evening in Mumbai and night in Tokyo.
| City | Local time when it is 12:00 UTC (15 January 2026) | UTC offset |
|---|---|---|
| New York | 7:00 am | UTC−05:00 |
| London | 12:00 pm | UTC+00:00 |
| Paris | 1:00 pm | UTC+01:00 |
| Dubai | 4:00 pm | UTC+04:00 |
| Mumbai | 5:30 pm | UTC+05:30 |
| Tokyo | 9:00 pm | UTC+09:00 |
| Sydney | 11:00 pm | UTC+11:00 |
| Los Angeles | 4:00 am | UTC−08:00 |
Two things stand out. First, the range: from 04:00 in Los Angeles to 23:00 in Sydney, the same instant covers almost the whole day. Second, the half hour: Mumbai is at 17:30, not 17:00 or 18:00, because India uses a half-hour offset (UTC+05:30). If you convert a time for Mumbai by rounding to the nearest hour, you will be half an hour out. The UTC converter shows the offset and the local time for any city on any date, and the time zone converter converts between any two cities directly.
The offsets change during the year for the cities that observe daylight saving. The same eight cities in January and in July:
| City | Offset in January 2026 | Offset in July 2026 | Changes? |
|---|---|---|---|
| New York | UTC−05:00 | UTC−04:00 | Yes — one hour |
| London | UTC+00:00 | UTC+01:00 | Yes — one hour |
| Paris | UTC+01:00 | UTC+02:00 | Yes — one hour |
| Dubai | UTC+04:00 | UTC+04:00 | No |
| Mumbai | UTC+05:30 | UTC+05:30 | No |
| Tokyo | UTC+09:00 | UTC+09:00 | No |
| Sydney | UTC+11:00 | UTC+10:00 | Yes — one hour |
| Los Angeles | UTC−08:00 | UTC−07:00 | Yes — one hour |
New York, London, Paris, Sydney and Los Angeles all change by one hour between January and July; Dubai, Mumbai and Tokyo do not, because they do not observe daylight saving. That is why a conversion done in January can be wrong in July — and why the UTC converter asks for the date.
Key facts
- UTC never observes daylight saving. It is the fixed reference that every other time zone is measured against.
- The world uses 38 different UTC offsets, from UTC−12:00 to UTC+14:00 — a span of 26 hours.
- Nepal is on UTC+05:45, the only 45-minute offset in regular use. India is on UTC+05:30.
- The Prime Meridian is at 0 degrees longitude, through Greenwich, London.
- A time written in UTC means the same thing everywhere on Earth, in January and in July.
Frequently asked questions
How do I find the time in another country?
Use the world clock: type the city and the time appears, with the date and the offset. Every major city has its own page on this site too.
What time is it in Tokyo now?
Tokyo is UTC+09:00 all year, so it is nine hours ahead of UTC. The world clock for Tokyo shows the live time.
How do I know if it is a good time to call?
Check the local time: 9am–5pm is working hours, 6pm–10pm is the evening, and 11pm–7am is the middle of the night. The world clock shows whether it is a reasonable hour.
Why do I need the date as well as the time?
Because a city 12 hours ahead is living in tomorrow. A call at 9pm in London is 6am the next day in Sydney — the date matters as much as the time.
How do I convert a meeting time to another country?
Use the time zone converter: enter the time in your city and it gives the time in every other city, with the date.
What time is it in Tokyo when it is 12:00 UTC?
23:00 the same day — Tokyo is UTC+09:00 all year, so you add nine hours to 12:00 UTC. In New York it is 07:00 in winter (UTC−05:00) and 08:00 in summer (UTC−04:00). The UTC converter shows the time in any city for 12:00 UTC.
What is the time difference between London and Tokyo?
Nine hours in January 2026: London is UTC+00:00 and Tokyo is UTC+09:00. In July it is eight hours, because London moves to UTC+01:00 while Tokyo stays on UTC+09:00. The time zone converter gives the difference for any two cities and any date.
